I want to get the DC bias value reading for a specific configuration with AD5933 impedance analyzer. That is, I want to read DC impedance value in addition to Re and Im data. Is it possible to get it?
The datasheet only guarantee reliable results at frequencies greater than 1KHz. This specification was indicated by the Transmit Stage section of the datasheet. Now, forcing the DAC to be DC is something that we haven't tested. But I suspect that the DFT could not resolve the DC resistance measurement since DC has an infinite period. We have a finite settling time parameter and DC has no period (infinite) so I think it requires a different method to measure DC resistance.
